P39.0

P39.0 — Neonatal infective mastitis

Billable / specific codeICD-10-CM

P39.0 is a billable, specific ICD-10-CM code for neonatal infective mastitis. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

breast engorgement of newborn (P83.4)
noninfective mastitis of newborn (P83.4)

Other codes that can never be billed with P39.0

These codes carry an Excludes1 note pointing at P39.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P39.0 alone.

N61Inflammatory disorders of breast

Risk adjustment

P39.0 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

How P39.0 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to P39.0.
